Introduction:Disaster Medical Response is a challenging field where opportunities for advancement are welcomed. Small Unmanned Aerial Vehicle (sUAV) technology (i.e., drones) has made enormous strides in the past few years and is poised for utilization in the early disaster response phase.Aim:To discuss current uses of UAVs, proposed utilization and logistical details, technological advancements, current deficits, and training.Methods:Our Foundation, Luman Medical, is working in the field of UAV integration for small to large scale disaster response. The concept is to equip first responders with small, relatively inexpensive, programmable drones that come equipped with hardware and software that are easy to use for inexperienced as well as skilled sUAV pilots.Discussion:These UAVs could increase ease and speed of deployment for early assessments of disaster area mapping, thermal imaging, ingress and egress routes, the discovery of survivors, communications, and delivery of supplies. Drone technology offers a new and growing type of tool in the disaster response arena. It is our hope to explore an integration that is easy, safe, and affordable to augment and enhance existing disaster response planning.

<p>Recently, climate change due to global warming has been frequented by large-scale weather disasters that have not been experienced in the past. Among various weather disasters, drought is one of the representative weather disasters in Korea recently along with heavy rains. In the case of drought, it occurs in a wide range in the short term and long term, and it is difficult to identify specific occurrence times, places, and causes, and damage and influence are enormous.</p><p>In the past, the Republic of Korea has been prepared with non-structural measures such as securing irrigation water for drought restoration, developing emergency management, and developing a drought information system based on drought index. The reduction measures for drought degradation were mainly used by Palmer Draught Severity Index (PDSI), Standardized Precision Index (SPI), Crop Moisture Index (CMI), Crop Specific Drug Index (CMI), and Profication (DICS Index), and Survey.</p><p>In this study, we intend to establish standards for reducing drought damage by investigating and analyzing drought damage characteristics in Korea. In the past, drought damage in Korea occurred in agriculture, living and industry, and the ministry manages and stores the data on drought damage. The drought damage in South Korea from 1965 to 2018 occurred a total of 204 times, mostly in South Gyeongsang and South Jeolla provinces, rather than in special cities and metropolitan cities. The purpose of this study is to analyze the characteristics of drought damage in Korea and establish the measures to reduce mega drought.</p><p>Acknowledges : This research was supported by a grant(2019-MOIS31-010) from Fundamental Technology Development Program for Extreme Disaster Response funded by Korean Ministry of Interior and Safety(MOIS).</p>

The naval shipyards are in the process of installing a system for identifying and recording specific job-related skills in their industrial workforce. The system, called the Shipyard Skills Tracking System (SSTS), is intended initially to support middle-level management in allocating their workforce properly for critical tasks and in accurately factoring personnel availability and training requirements into the planning for upcoming work. SSTS is supported by sophisticated computer programs which are integrated into other shipyard administrative programs. Data entry, ever the bugaboo of large-scale tracking programs, is minimized by using data links to other job-related programs for most of the information. The programs have been successfully field-tested at one naval shipyard and, starting in November 1989, began undergoing phased installation at all eight government yards. Discussion John D. Prebula, Pearl Harbor Naval Shipyard This paper is an excellent overview of how shipyards will track qualifications, skills, skill level, and other data needed to assign work. The SSTS is a good example of what can happen when appropriate technology is used to satisfy similar needs at a number of naval shipyards. The naval shipyards had a problem where they knew a great deal about the training and qualifications of individuals but had poor means of retrieving the information on their skill level. Attempts in the past to document and retain the information on skill levels and experience were generally unsuccessful because of the large amount of information and the continuing changes in the information. The SSTS successfully linked new microcomputer technology and training information in the shipyard main-frame computer. This allows information to be maintained currently and easily without the large duplication of effort that had been necessary in the past. Pearl Harbor Naval Shipyard's supervisors are looking forward to full implementation of the SSTS and believe that if properly implemented it will be of benefit to the shipyard. Mr. Hartigan does an excellent job of listing and explaining the important features of the SSTS and uses the example of a new supervisor trying to provide someone for a "tiger team" effort. While such a system is definitely a benefit to new supervisors it is also a great benefit to supervisors who have been on the job and know the people rather well. An experienced supervisor who is familiar with his people is still not likely to know such things as:who has passports, the currency of medical exams, the currency of inoculations, and, the other things necessary to be checked out before someone can be sent overseas or to a specific shipyard job. When the workforce is composed of a large number of temporary or more transient workers (as shipyards are being asked to become), the importance of a system to track skills becomes more important than ever. The SSTS, as the author explains so well, is not just another system of tracking qualifications. Rather, it marries together qualifications, skills, skill levels, some select training, medical qualifications and selected attributes such as the possession of a passport. This database is updated for training and qualification whenever the shipyard's mainframe is updated for these trainings and qualifications. The SSTS is manually updated for the specific attributes and skills. It was the marrying of the microcomputer technology to the shipyard's main-frame computer that allowed such a system to come into existence without the need for the purchase of additional computer equipment. As planned, the shipyard's SSTS system will be applicable to the production department workers for all ships in the shipyard and will be applied to selected engineering and inspection codes. One significant item in the paper is the mention that not only are the skills and experience reported and tracked, but the degree of expertise in each of these skills is also tracked. Mr. Hartigan uses the words "accomplished a battery replacement successfully." This allows the shipyard not only to track who has performed specific skills or tasks, but to know at what level they are capable of performing. This is done by a tie between the timekeeping system and the SSTS, allowing the supervisors to annotate the skill level when an individual has done a specific skill by entering the appropriate coding on the timekeeping sheet. This timekeeping entry also provides direct input into the SSTS.

In wireless rechargeable sensor networks, most researchers address energy scarcity by introducing one or multiple ground mobile vehicles to recharge energy-hungry sensor nodes. The charging efficiency is limited by the moving speed of ground chargers and rough environments, especially in large-scale or challenging scenarios. To address the limitations, researchers consider replacing ground mobile chargers with lightweight unmanned aerial vehicles to support large-scale scenarios because of the unmanned aerial vehicle moving at a higher speed without geographical limitation. Moreover, multiple automatic landing wireless charging PADs are deployed to recharge unmanned aerial vehicles automatically. In this work, we investigate the problem of introducing the minimal number of PADs in unmanned aerial vehicle–based wireless rechargeable sensor networks. We propose a novel PAD deployment scheme named clustering-with-double-constraints and disks-shift-combining that can adapt to arbitrary locations of the base station, arbitrary geographic distributions of sensor nodes, and arbitrary sizes of network areas. In the proposed scheme, we first obtain an initial PAD deployment solution by clustering nodes in geographic locations. Then, we propose a center shift combining algorithm to optimize this solution by shifting the location of PADs and attempting to merge the adjacent PADs. The simulation results show that compared to existing algorithms, our scheme can charge the network with fewer PADs.

Unmanned aerial vehicles (UAV) have gained tremendous interest as a platform for surveying and mapping over the last few years, and have opened up a new realm of opportunities for surveying, orthophoto production, 3D modelling and feature extraction. UAVs provide a viable and affordable alternative for the airborne and space borne sensors for the medium/large scale mapping. This paper argues that universities should expand their education and training programs to include UAV-based geomatics operations and application development. Based on the author’s own experience as well other cases, details are developed and presented in this paper with respect to the likely syllabi and practical assignments. Alternatives for hardware and software support will be briefly discussed.

The number and the scale of natural disasters have drastically increased over the last decades. One of the most vital stages of disaster preparedness is disaster response planning, and it plays an important role in limiting material and immaterial consequences, such as those caused by large scale earthquakes. In order to minimize human suffering and death, the aim of establishing a well-designed humanitarian relief chain must be to provide medicine, water, shelter, emergency food and supplies to the affected areas. From a holistic perspective, providing timely first aid and rapid transfer of injured victims to a medical facility is one of the most essential component of such chain. Thus, the location of first aid hospitals must be determined following a careful thought and planning process. This study presents a fuzzy integer programming model to determine the best location of the temporary hospitals which are expected to support extant state hospitals after a major earthquake. This study applies the proposed fuzzy model to the Üsküdar province of Istanbul and identifies optimum number and locations of field hospitals for a severe earthquake scenario.

In recent years, the area of Unmanned Aerial Vehicles (UAVs) has seen rapid growth. There has been a trend to build and produce UAVs that can carry out planetary exploration throughout the past decade. The technology of UAVs has tremendous potential to support various successful space mission solutions. In general, different techniques for observing space objects are available, such as telescopes, probes, and flying spacecraft, orbiters, landers, and rovers. However, a detailed analysis has been carried out due to the benefits of UAVs relative to other planetary exploration techniques. The deployment of UAVs to other solar bodies has been considered by numerous space agencies worldwide, including NASA. This article contributes to investigating the types of UAVs that have been considered for various planetary explorations. This study further investigates the behaviour of UAV prototypes on Mars’ surface in particular. It has been discovered that a prototype UAV flight on Mars has a higher chance of success. In this research, a prototype UAV has been successfully simulated to fly on Mars’ surface. This article discusses the opportunities, challenges, and future scope of deploying UAVs on Mars.

BackgroundThis is the third large-scale audit in the past 20 years and compares the practice of electroconvulsive therapy (ECT) in England and Wales with the standards derived from the Royal College of Psychiatrists' 2nd ECT handbook.MethodFacilities, equipment, practice, personnel and training were systematically evaluated during visits to all ECT clinics in the former North East Thames and East Anglia regions and Wales. All other English ECT clinics were surveyed with a postal questionnaire. Information was obtained for 184 (84%) of the 220 ECT clinics identified.ResultsAlthough some aspects of ECT administration had improved since the last audit in 1991, overall only one-third of clinics were rated as meeting College standards. Only 16% of responsible consultants attended their ECT clinic weekly and only 6% had sessional time for ECT duties. Fifty-nine per cent of all clinics had machines of the type recommended by the College and 7% were still using machines considered outdated in 1989. Only about one-third of clinics had clear policies to help guide junior doctors to administer ECT effectively.ConclusionsTwenty years of activity by the Royal College of Psychiatrists and three large-scale audits have been associated with only modest improvement in local practice.
